Problems solved by technology
Due to the limitation of test conditions, there are not many tests on offshore platform pipes and pipe joints at present. In particular, the test equipment used for collision impact can only be used for impact tests of pipes and pipe joints of a single specification. Pipe joints must be specially designed and processed with a set of test tooling, which increases the cost of the test

The invention discloses a T-shaped pipe node impact test device for an ocean platform, and opening ends of two moving outer frames respectively accommodate two ends of a fixed inner frame. The moving outer frames are fixedly connected with the fixed inner frame through moving outer frame locking mechanisms. The two moving outer frame locking mechanisms are symmetrically disposed in longitudinal ends of the fixed inner frame, and a moving outer frame supporting mechanism and a moving outer frame lifting mechanism are disposed between each moving outer frame and a base plane. T-shaped pipe fixing mechanisms are disposed on outer ends of the two moving outer frames, and T-shaped pipe measurement mechanisms are disposed at outer sides of the T-shaped pipe fixing mechanisms. A method comprises the steps: adjusting the distance between vertical supporting plates, and locking the connection between the fixed inner frame and the moving outer frame. The device can be suitable for the impact test of various types of T-shaped pipe nodes, is high in universality, and reduces the test cost. The method can precisely obtain the plastic deformation value of the T-shaped pipe nodes.
Description
technical field [0001] The invention relates to an impact test device and method for pile legs of an offshore platform, in particular to a test device and method for the dynamic response of damage and deformation of T-shaped tubular joints under drop hammer impact load, belonging to the technical field of marine engineering. Background technique [0002] As the main component of marine energy exploration and development, offshore platforms are the main operating bases for offshore oil and gas exploration wells, drilling and exploitation. Among all kinds of offshore platform structures, the jack-up offshore platform occupies the main force in offshore oil and gas development and exploration due to its good positioning capability and operational stability. There are usually ships operating in the sea area around the offshore platform, or the offshore platform itself is located in the main channel, which greatly increases the probability of ship collision. According to statist...
